SPECIFICATION forming part of Letters Patent No. 788,343, dated April 25, 1905.

Application filed August 20, 1904. Serial No. 221,589.

,To n/Z/ 11711/0771/ it 777,/1/ 7/ conc/27%.-

Beit known that I, VILLIAM ACKERMAN, a citizen of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented new and useful Improvements in W elleDrilling Machinery, of which the following is a specification.

.My invention relates to well-drilling machinery; and its object is to provide improved mechanism of this character which is of durable and compact construction and which is provided with means whereby the various parts thereofl are under the absolute control of the operator at all times.

Another object is to provide a novel arrangement of friction-wheels for transmitting rotary motion from the drive mechanism to the other operative portions ofthe machine.

Vith the above and other objects in view the invention consists of the further novel const-ruction and combination of parts hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings I have shown the preferred form of my invention.

In said drawings, Figure 1 is a side elevation of the machine, the upper portion of the mast being removed, as well as therear end of the platform. Fig. 1a is a side elevationY of that portion of the mast removed from Fig.

1 above line A A. Fig. 1b is a side elevation of that portion of the platform removed from Fig. 1 beyond line B B. Fig. 2 is an enlarged vertical longitudinal section through the central portion of the platform and showing the drive mechanism in elevation. Fig. 3 is a top plan view of the central portion of the machine. Fig. 4 is a side elevation of the lower portion of the mast and showing its walking-beam disconnected from the main drive-shaft, and Fig. 5 is a section through one end o f the bullwheel shaft.

Referring to the figures by numerals of reference, 1 1 are the mud-sills of the platform, and on these sills are arranged the main sills 2. Arranged upon the platform adjacent the center of the machine are standards 3 and 4,"in which is journaled a main drive-shaft 5, having' a crank 6 at one end, from which extends a wrist-pm 7. A master friction-wheel 8 is secured to and rotates with this shaft, and a drive-wheel 9 is also secured to the shaft and is adapted to be rotated by a belt extending from an engine. (Not shown.) The standards 3 and t are suitably braced by means of lixed strips lO and adjustable rods 11, and rods 12 also extend along the sides of the standards 3 and from the platform of the machine. These rods l2 engage the caps 13 of the bearings of shaft 5, thereby preventing the shaft from working loose. Pivoted to one of the brace-strips 10 and hanging therefrom is a metal hanger 14, the lower or free end of which is connected by a rod '15 with a lever 16, pivoted to the platform adjacent the forward end thereof and having a toothed segment 17 for 'locking it in adjusted position. This hanger forms the bearing for oneend of a shaft 18, the other end of which rotates within a'bearing 19, mounted on a standard 20. A sand-line drum 21 is arranged on and rotates with the shaft 18, and a friction-pulley 22 is secured to the shaft 18 adjacent one end of the drum Q1 and below and in alinement with the friction-wheel 8. An upright 23 is located upon the platform and in rear of pulley 22 and has one face cut away or concaved, as shown at 24, to receive the periphery of pulley 22.

Revolubly mounted in standards 25 and 26, which are strengthened by means of lixed braces 27 and adjustable rods 28, is a shaft 29 of a bull-wheel 30. This bull-wheel is in alinement with friction-wheel 8. A brakewheel 31 is secured to the shaft 29, and a brake-band 32 contacts with the periphery thereof and is rigidly secured at one end, while its other end is connected, by means of a rod 33, with a lever 34, having a toothed segment 35, whereby it may be locked in adjustedposition. A cross-strip 3G connects the standards 4: and 26 and has a strap 37 thereon, which forms a guide for a slide 38. A friction-wheel 39 is journaledat one end of this slide and is located between the two frictionwheels 8 and 30, and the strip 38 isconnected to a bell-crank lever AO. This bell-crank lever is connected, by means of a rod 41, with a lever 4t2, having a segment 43 for locking it in adjusted position. Friction-wheel 39 is so IOO located that when the same is drawn downl ward it is caused to contact with the peripheries of the wheels 8 and 30, and therefore transmit rotary motion from one to the other.

A mast 44 extends upward from the platform and is provided with a suitable brace 45. This mast has a sheave 46 journaled within it adjacent its upper end and another sheave, 47, journaled in the end of the mast. A walking-beam 48 is pivoted in the mast and has a pitman 49 pivoted to one end and adapted to be connected to the wrist-pin 7 of crank 6.

Arranged adjacent one end of the platform is an engine-base 50, which is adjustably connected, by means of overlapping beams 51 and 52, to the end of the platform. These beams are held together by straps 53, and an adjusting-screw 54 connects the beam 52 with base 50. By operating this screw said base can be drawn from or toward the platform so as to loosen or tighten the belt, which is ad apted to extend from an engine on the base 50 to the main drive-wheel 9.

After the mast 44 has been properly placed upon the platform the walking-beam 48 can be operated by rotating the main drive-wheel 9^. Crank 6 will cause the pitman 49 to operate the walking-beam. To rotate the sand-line drum, it is merely necessary to draw backward on lever 16, and hanger 14 will press the friction-wheel 22 against friction-wheel 8, and the drum 21 will therefore be caused to revolve and wind the sand-line upon it. By pressing levell 16 in the opposite direction friction-wheel 22 will come in contact with the bearing-face 24 of back brake 23 and will be held against rotation. By operating lever 42 bell-crank lever 40 can be swung so as to draw friction-wheel 39 into contact with friction-wheel 8 and bull-wheel 30. Motion is thus imparted from the main drive-shaft 5 to the shaft of the bull-wheel, and the cable connected to said shaft will thus be wound thereon. Shaft 29 can be held against rotation by drawing on lever 34 so as to tighten the band 32 on brake-wheel 31. The pitman 49 may be disconnected from the Wrist-pin 7 and a spudding-wheel 55 placed thereon.

The machine herein described is of compact construction, and by arranging all of the parts upon one platform composed of mud and main sills there is no danger of any of the parts rising or becoming displaced, particularly in View of the strong braces and retaining-rods which are employed. All of the levers for controlling the machinery are arranged at points within' convenient reach of the operator. The sand-line is adapted to run from the drum and over the upper sheave 47 on the mastand 1s for the purpose of raising or lowering the sand-pump.

In the foregoing description l have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new is 1. In a rig of the character described, the combination with a platform having a main drive-shaft thereon, and a friction-wheel upon the shaft; of a second shaft above the platform, a bull-wheel mounted thereon, a slide interposed between the friction and bull wheels, a friction-pulley upon the slide adapted to move into. or out of contact with the friction and bull wheels, and means for operating the slide.

2. In arig of the character described, the combination with a platform having a mast thereon, and a sheave upon the mast; of a main drive-shaft journaled above the platform, a friction-wheel upon the shaft, a second shaft journaled above the platform, a bull and a brake wheel arranged thereon, a slide interposed between the friction and bull wheels, a power-transmitting pulley upon the slide, and means for shifting the pulley into and out of contact with the friction and bull wheels.

3. In a machine of the character described, the combination With a platform having a mast thereon, and a sheave upon the mast; of a main drive-shaft journaled above the platform, a friction-wheel thereon, a crank revoluble with the shaft, a spudding-wheel on the crank, a second shaft journaled above the platform, a bull-wheel thereon, a slide interposed between the friction and bull wheels, a powertransmitting pulley on the slide, and means for moving the pulley into or out of contact with the adjacent Wheels.

4. In'a machine of the character described, the combination with a platform having a derrick thereon; of a shaft journaled above the platform, a brake-wheel and a bull-w heel upon the shaft and revoluble therewith, a brakeband inclosing the brake-wheel, a main driveshaft, a friction-wheel thereon, a slide interposed between the bull and friction wheels, a friction-pulley upon the slide, means for moving the pulley into or out of contact with the friction and bull wheels simultaneously, a crank revoluble with the main drive-shaft, and a spudding-wheel upon the crank.

In testimony whereof I aiiiX my signature in presence of two witnesses.

WILLIAM ACKERMAN.
